Análise da qualidade dos serviços das piscinas públicas cobertas da Madeira na perspectiva dos utentes do setor lazer e recreação

O propósito do estudo foi estudar a qualidade do serviço das piscinas públicas cobertas da RAM através do índice de satisfação dos utilizadores do setor lazer e recreação, bem como identificar o perfil destes praticantes. O estudo envolveu a participação de 410 utilizadores regulares, integrados em atividades de clubes ou outras entidades e de nado livre, maiores de 16 anos, os quais foram inquiridos através da aplicação de um questionário individual e anónimo. Os resultados do estudo indicam que o perfil dos praticantes do setor lazer e recreação se caracteriza por utentes, prioritariamente, do sexo feminino, com idade igual ou superior a 46 anos, empregados, tendo no cômputo geral, no máximo o 3º ciclo do ensino básico. Foram pessoas ativas ao longo da sua vida e deslocam-se à piscina duas a três vezes por semana. Frequentam as piscinas, maioritariamente, devido a problemas de coluna, articulares e ósseos, para melhorar a sua condição física, para efetuar reabilitação ou recuperação física, ou para reduzir o stress e descontrair. Como benefícios alcançados com a prática da natação/hidroginástica, consideram a melhoria da condição física, a redução das dores nas costas, articulações e ossos, e a melhoria do estado geral da sua saúde. Na generalidade, os utentes encontram-se satisfeitos ou muito satisfeitos com a avaliação dos parâmetros relativos aos materiais e equipamentos, higiene e segurança, temperatura da água, atendimento e simpatia dos trabalhadores e com os horários de funcionamento das piscinas. Constatámos ainda a existência de uma relação direta entre as razões que levaram à prática de atividades aquáticas e a autoperceção dos benefícios alcançados com a sua realização. No que diz respeito à definição da qualidade do serviço prestado ao nível das diversas dimensões estudadas, concluímos que os utentes das piscinas em estudo consideram que lhes é prestado um serviço com elevada qualidade.

Relações interorganizacionais e confiança no setor da carcinicultura: um estudo de caso na camanor produtos marinhos

This study investigated how the types of confidence based on competence and good will act in the formation and maintenance of cooperation relationships between the Camanor and its partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). It used organizational approaches on networks based primarily on studies of Powell (1987, 1990), Das and Teng (2000, 2001), Child (2001) and Contractor and Lorange (2004) which have described the advantages that cooperative relationships can provide, as well as their limits as alternative governance structures. Confidence has been considered an important factor affecting the actions and development of organizations involved in networks or in strategic alliances (ZAHEER; HARRIS, 2006) and is the most appropriate control mechanism in these situations (SYDOW, 1998). Confidence is seen from two different approaches: the economic and the sociological (ZAHEER; HARRIS, 2006). To facilitate the understanding of confidence some typologies have been created, as proposed by Barney and Hansen (1994), Lane (1998), Das and Teng (2000), Child (2001) and Wever, Martens and Vandenbempt (2005). This study made use of the case study as proposition of Yin (2005). Semi-structured interviews were held with pre-determined routes, in a single stage performed in early 2008. The research subjects were owners and / or responsible for Camanor and its business partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). Also secondary data were collected in several sites related to the industry and enterprises studied, in addition to data collected by previous studies conducted by CARCINEREDES (2006). The primary data were analyzed using the analysing technique of the content proposed by Bardin (1994). Regarding the secondary data, they were qualitatively analyzed according to documentary analysis technique (BARDIN, 1994). Thus, through the data collected, could be concluded that although there is confidence based on good faith in relationships(UZZI, 1998; OF; TENG, 2001), their presence does not determine the formation and / or maintenance of a partnership, serves only in order to facilitate the relationship, making them more flexible. The confidence based on competence (DAS; TENG, 2001) influenced the formation and maintenance of relations studied. Because whether or not to form a relationship with another organization it is used the perception of the partner acts, namely the reputation (image) as decision basis. And it is through the verification of the performance of the partner activities that will determine the continuation of the partnership

O uso do móbile marketing como estratégia de fidelização de clientes :um estudo e empresas do setor de comércio e serviços em natal-RN

This study aims to understand the effects of the mobile marketing use as a relationships tool for companies that operate locally, because of the lack of information about this new marketing tool, as well as the scarcity of studies in this area. This is an exploratory and qualitatively study, based on primary sources, raised through books, articles in the marketing area and the telecommunications industry organs as well as secondary sources. With the purpose to look into the issue, a semi-structured interview is made with the companies managers of the sectors of trade and services in Natal-RN. The advances in technology allow an important discussion focused on the marketing in the new communication technologies scenario. It appears that the mobile marketing adoption and use by local companies is already a reality and companies are awake to changes and technological innovations accessible, especially the mobile telephony as well as convergence with other media. There is, however, that the use of technologies offered by mobile marketing is still limited to the sending of text messages (SMS), despite the numerous possibilities of it use. Moreover, the results obtained with mobile marketing use show that companies can identify them, but there is no effective monitoring in quantity and financial terms. Only affect sales growth and support for progress in loyalty with customers. It shows up that the mentality of not measuring the results still in the plan of changes and technological innovations. The data allow saying that the mobile marketing is a reality, however has not yet signed as a tool for carrying out campaigns and marketing tool for loyalty of customers, despite presenting a wide range of possibilities to streamline and make more effective the marketing businesses process

As relações da tríplice hélice no setor da carcinicultura do Rio Grande do Norte: uma análise a partir das abordagens da imersão social e da dependência de recursos

This work consists in a study of the Shrimp Industry in the state of Rio Grande do Norte, whose central issue relates to the understanding of how the Triple Helix (University, Government and the productive sector) interrelationship limits or expands the industry s innovation process. The study aims to understand how the Triple Helix relationship interferes in the innovation process of shrimp in Rio Grande do Norte. As the knowledge becomes the resource key for production methods, the generation of new technologies, new products and processes which demands joint and integrated action of the institutions comprising the Triple Helix: University, Government and productive sector, which possess the essential resources to innovate the process and can be maximized from cooperative relationships between the referred Institutions. Thus, in this work, it was sharply used the pioneering studies of Sabato and Botana (1968) regarding the cooperation relationship between the scientific-technological sphere, the governmental and the productive base, and studies on the Triple Helix approach, proposed by Etzkowitz and Leydesdorff (2000), in which the university has a key role in the process of technological and innovative development of countries and regions, and under which it is assigned to the very University - the character of the entrepreneurial institution, through the concept of entrepreneurial University. Aiming to overcome the criticism of Cooke (2005), regarding the limitations of the Triple Helix approach, in this study it was used - as analytical perspectives - the perspective of social immersion (Granovetter, 1985, 2005) and the theory of resources dependence (PFEFFER; SALANCIK, 1978). The analytical perspectives presented in here, despite of the different assumptions, are essential to eliminate the bias that one only approach can lead (ASTLEY; VAN DE VEM; 2007). The authors arguments focus on the fact that the integration is possible if the researcher acknowledged that different perspectives may have different descriptions of the same phenomenon. As a research strategy, this study is characterized as a study case, along with the proposed objectives - the qualitative method was used as an approach and, depending on the gathering of the sector s historical, a sectional longitudinal view approach was applied (VIEIRA, 2004). The primary and secondary data were used in order to understand the sector s evolutionary process and its inter-institutional relations - regarding the shrimp culture in Rio Grande do Norte - to promote the development, as the content was used for the technical analysis (BARDIN, 1977). The approach of social immersion and resources addiction dependence made it possible to understand that relationships are established within and between each sphere (university, government and productive sector) characterizing a network of low density relationships and strongly internal and external dependence. Based on the speech of Etzkowitz and Mello (2006), a successful Triple Helix strategy of innovation requires not only the involvement and commitment of the parts, within the institutional sphere and among them, but also the development of mechanisms to coordinate the multiple and complex interactions and interfaces, focusing on promoting both environment and context for innovation and learning; it can be acknowledge from study results that the shrimp in the State of the RN, although there are several institutional mechanisms to promote greater integration and technological development, has been presented disjointed - both internally and between the spheres - and under no legitimate practice when facing the innovational promotion and integration institutions. Due to those factors, the central institutions of the network are crucial to the promotion of innovations, spreading through their direct contacts the importance factor of the sustainable competitive activity in the world market and on the national level. However, it may be concluded, from the data, that the Triple Helix relations are interfering in a negative way on what concerns the promotion of innovations in the shrimp industry in RN
